ELECTRICITY DEMAND AND FORECAST WORKSHEET

PURPOSE AND INSTRUCTIONS
Use a load curve or utility forecast with its definitions. Separate energy (MWh), average power (MW) and interval peak (MW). This is a reading worksheet, not a resource-adequacy study.

SOURCE
Region / report / publication date / forecast year:
Time zone / interval length:
Boundary: customer consumption, grid load or defined net load:
Treatment of behind-the-meter generation, imports and losses:
Weather / economic / electrification / new-load assumptions:
Status of new loads: announced, contracted, connected, operating:
Central / high-low / extreme-condition cases:

LOAD CALCULATION
For each interval: average MW x hours = MWh.
Sum interval MWh for period energy:
Average MW = total MWh / total hours:
Peak MW at the stated interval:
Load factor = average MW / peak MW x 100%:

FICTIONAL DAY
50 MW x 8 h = 400 MWh
80 MW x 8 h = 640 MWh
100 MW x 4 h = 400 MWh
60 MW x 4 h = 240 MWh
Total = 1,680 MWh; average = 70 MW; peak = 100 MW; load factor = 70%.
Shift 10 MW from each of the four 100 MW hours into four of the 50 MW hours:
Energy remains 1,680 MWh; peak becomes 90 MW; load factor becomes 77.8%.
This assumes shifting causes no added consumption; check rebound and process constraints in real cases.

RESOURCE QUESTIONS
Required MW and hours / season / event frequency:
Availability, outages, fuel/weather exposure and correlated risks:
Storage usable MWh and charging opportunity / dependable demand response:
Import deliverability / transmission constraint:
Fictional 10 MW for 4 hours requires 40 MWh delivered, before accounting for charging, reserves or losses.
Forecast-versus-actual history / delivery dates / contingency if demand arrives early:
Decision or questions for planner:
